In this WHERE clause, I have parentheses:

WHERE Client.NoProvince=@NoProvince AND
 NOT (Client.Status<@Status AND Client.NoStatus=@NoStatus) AND
 NOT (Client.Status<@Status2 AND Client.NoStatus=@NoStatus2) AND
 NOT (Client.Status<@Status3 AND Client.NoStatus=@NoStatus3) AND
 NOT (Client.Status<@Status4 AND Client.NoStatus=@NoStatus4) AND
 Client.NoCountry IN (1,2,3,4,5,6,7) AND
 Client.FirstName LIKE @LXList1Clm_No

Would there be a way to avoid the parentheses? I see the execution is much smarter without those.
